Laney Iommi TI15-112, Operating Instructions Manual

FRONT PANEL CONTROLS

15W INPUT: 

1/4" mono jack socket. Connect your guitar here to get full volume output. Use only high quality guitar cable.

<1W INPUT: 

1/4" mono jack socket. Connecting your guitar here switches the output stage to under 1W.  This allows you 

to drive the output stage hard at bedroom volume levels. 

Note: Both sockets should not be used simultaneously.

PRE-BOOST SWITCH: 

Switches the input boost circuit on or off. The Pre-Boost circuit increases the input signal to the 

preamp tubes, just like placing a boost pedal in your signal path. This drives the preamp tubes harder, resulting in more 
distortion.

PRE-BOOST CONTROL:

 Controls the level of boost applied to the guitar signal.

PRE-BOOST LED: 

This LED will illuminate when the Pre-Boost controls are activated.

DRIVE: 

Controls the level of preamp distortion. Turning this control clockwise will add more distortion to your guitar 

signal, ranging from light overdrive, to full on metal. Use this in conjunction with the Volume Control (6) to achieve the 
correct volume and distortion level you require. With the volume control below 6, you will get preamp distortion. 
Turning past 6 will add power amp distortion.

EQ CONTROLS: 

These are a traditional set of passive tone controls. Passive controls have the advantage of always 

sounding musical at any of their settings, due to their unique interactive nature. This gives the player a more natural set of 
tools to shape their ideal sound. Set these midway at (5) as a good starting point.
